I have been using my Picoscope 6404D with Matlab 32 bit successfully for some time, but would now like to use with 64 bit Matlab 2014b.

I have installed Windows 7.1 SDK on my PC, and downloaded the SDK for the 6404D from the picoscope website. From this download I have copied the files in the x64 directory to a location on my Matlab path. I also found a new version of PS6000MFile.m on a thread in this forum which seemed to be for use with 64 bit Matlab.

I then tried

loadlibrary('ps6000.dll','PS6000MFile')

as I used to do previously

This time I got the error:

Error using loadlibrary (line 440)The specified module could not be found.

Could you please advise what steps I need to take to successfully load the 64 bit version of the dll?
